Hello.


When I clicked the point of the red frame, I do not want to perform On/Off of the check box.

When I clicked the point of the green frame, I want to perform On/Off of the check box.

Here is the required update for the drag-n-drop detection methods:

bool CExtControlBar::stat_DragDetect_ImplStep(
      HWND hWnd,
      POINT pt,
      UINT nUpMessage // = WM_LBUTTONUP
      )
{
      if( hWnd == NULL || (! ::IsWindow( hWnd ) ) )
            return false;
CSize sizeDrag( ::GetSystemMetrics( SM_CXDRAG ), ::GetSystemMetrics( SM_CYDRAG ) );
CRect rc( pt.x - sizeDrag.cx, pt.y - sizeDrag.cy, pt.x + sizeDrag.cx, pt.y + sizeDrag.cy );
      ::SetCapture( hWnd );
      for( MSG _msg; ::IsWindow( hWnd ) ; )
    {
        for(      ;
                        ::IsWindow( hWnd )
                  &&    (     ::PeekMessage( &_msg, hWnd, WM_MOUSEFIRST, WM_MOUSELAST, PM_NOREMOVE )
                        ||    ::PeekMessage( &_msg, 0, WM_CANCELMODE, WM_CANCELMODE, PM_NOREMOVE )

            }
       }
        ::WaitMessage();
    }
    return false;
}

      return false;

The check box does not react even if I click check box.
